How to use a telescope properly?
Nowadays, with the rapid development of science and technology, the telescope is no longer just a rare thing for a few people to do scientific research, but a good helper for people to relax, cultivate interest and enlighten education.
With the improvement of living standards, a large number of curious teenagers and adults with childhood dreams have joined the ranks of astronomy enthusiasts. But with so many telescopes on the market, how will the novice enthusiast know how to use a telescope properly? So follow me to find out.
1. How to use a telescope properly?
Proper use of telescopes:
The first step is to adjust the distance between the two tubes of the telescope until the left and right view is a circular field of view so that the distance between the pupil of the two tubes is the same as that of the human eye. The distance between the pupil of the eye varies from person to person. When you observe a scene with a binocular telescope, if the field of view of the left and right eyes does not coincide, the scene will not have stereoscopic vision (scene hierarchy).
This means that the pupil distance of the telescope does not coincide with your pupil distance and needs to be adjusted. The method is to turn the two scopes of the telescope outward larger or inward smaller until the two eyes observe the scene into one image, the two fields of view completely coincide, the general distance between the pupil of the telescope can be adjusted between 50-72mm, to ensure the best observation effect.
The second step, first closes the right eye, with the left eye to look out, turn the telescope’s adjustment mechanism (handwheel or pressure plate), until clear; With the left eye closed, look out with the right eye and adjust the right eye mask (rotate slowly from left to right) until it is clear.
The third step is to point the telescope at the target and slowly turn the central adjustment mechanism. The eyes can quickly see the target. For targets with different distances, the target can be seen clearly only by adjusting the middle adjusting mechanism.
In the fourth step, first, pull the doubling bar to the minimum multiple, adjust with the above method. After the goal is clear, pull the multiplication bar and select the appropriate multiple you need.
2. The use of binoculars
Step 1: Take out the telescope, open the objective lens and eyepiece cover, students wearing glasses, rotate the eyepiece adjustment knob, adjust to the appropriate exit pupil distance.
Step 2: Close the right eye, align the left eye with the object to be observed, and slowly center the focusing wheel clockwise or counterclockwise, subject to the object clearly observed with the left eye.
Step 3: close the left eye and align the right eye with the object to be observed. Slowly adjust the knob clockwise or counterclockwise with the object clearly observed by the right eye.
Step 4: Hold the endoscopic body with both hands, observe the left and right visual fields at the same time, until the two visual fields coincide completely.
Step 5: When observing objects at different distances, align with the observed objects and adjust the center rotation focusing wheel with your right hand.
3. The last word
In the snow, strong light, smoke, and other different weather conditions, to install the corresponding filter, in order to reduce the snow, strong light to the human eye stimulation, increase the background of the smoke. When using a telescope with an infrared light-sensitive screen during the day, unpull the infrared light-sensitive screen to avoid darkening the mirror room and reducing the field of vision caused by the light-sensitive screen, which will affect the observation effect.
When the long-term storage of the telescope is enabled, it should be carefully checked, found that the lens of mold, fog phenomenon to wipe clean; Check that the optic adjuster and the connection between the pupil spacing are normal. At ordinary times, it should be properly kept to prevent scratching the mirror surface, keep clean and dry, and avoid dampness.
